Abstract

Color television display apparatus incorporating a television display tube and first and second deflection coil units arranged around the neck of the display tube in the deflection region to deflect at least one electron beam into two orthogonal directions when an associated deviation current is applied to each coil unit, characterized in that a quadrupole field is generated in the deviation region to correct asymmetries, finding the geometric axes of said quadrupole field generated substantially along the diagonals between the axes of the deflection directions, said quadrupole field being substantially proportional to the deflection current flowing through at least the first deflection coil unit.
